Cube's FP&Agents need a write-authority close map

Name the financial state before naming the agent

Start with the object that could change: source-system extract, staging table, account mapping, forecast assumption, working model, management report, board deck, journal-support schedule, or close checklist. For each object, distinguish read, calculate, propose, write to a sandbox, submit for approval, publish to a working model, and certify for reporting. An agent that can draft a forecast update should not inherit authority to overwrite the approved baseline; an agent that can identify a mapping exception should not clear it merely because a suggested mapping is plausible. Put the legal entity, period, scenario, currency, owner, source system, and current approval state on every proposed write. The CFO's control question is not whether the agent has write access in the abstract. It is which object may move from which state to which next state, on whose evidence, and before which cutoff.

Make approval evidence specific to the change

Define the evidence required by task rather than accepting one generic human-review step. A variance explanation may need a reconciled source extract and materiality threshold. A chart-of-accounts mapping may need the source account, target account, effective period, entity scope, preparer, reviewer, and downstream reports affected. A forecast assumption may need its business owner, prior value, new value, reason, scenario, and sensitivity. A board-deck figure may need reconciliation to the approved management-report version. Record the agent's proposal separately from the reviewer's decision, including any edits and the exact version approved. Source tracing can help a reviewer inspect inputs; it does not establish that classification, completeness, elimination, timing, or judgment is correct. Approval is meaningful only when it identifies what the reviewer actually verified.

Test the close boundary and the reversal path

Run the pilot through a representative close calendar. Confirm what happens when an agent finishes after a subledger cutoff, when actuals are reloaded, when a mapping change affects prior periods, when a user has different permissions across entities, and when the same task arrives through a spreadsheet, chat surface, or MCP-connected assistant. Require idempotency or duplicate detection for repeat runs. Every accepted write should retain the before value, proposed value, approved value, actor, timestamp, originating surface, model or workflow version, and downstream artifacts touched. Reversal must restore a known state without erasing the original event. Freeze or narrow agent write authority during defined close windows, and route reopened periods, consolidation adjustments, disclosure figures, and journal-affecting work through the applicable controllership process.

Reconcile the audit trail to finance's system of record

Before expansion, select a sample from agent requests through final finance output and reconcile four records: the source transaction or approved assumption, the agent action log, the human approval, and the resulting model or report version. Measure unsupported suggestions, rejected changes, overrides, duplicate actions, late writes, broken source links, permission exceptions, and reversals—not only time saved or tasks completed. Assign owners for access recertification, mapping policy, model governance, incident response, vendor changes, and evidence retention. Keep provider logs as one input to the finance control record, not the only record. The release decision should say which tasks remain read-only, which may produce proposals, which can write to controlled working states, and which remain prohibited until design and operating effectiveness are supported by evidence.

Turn this source into a reviewable decision

For AI for CFOs, use this briefing as a dated decision record rather than a substitute for the source. Preserve FP&Agents: Purpose-Built AI Agents for FP&A, the exact URL, the September 5, 2026 review date, the supported facts above, the editorial interpretation, the limitations, and any buyer-specific evidence. Link that record to the decisions most directly affected: Close, reconciliation, and variance investigation; Planning and scenario analysis; Internal control and audit evidence; Management reporting and external disclosure support. State whether the source changes the scope, evidence requirement, control, sequence, or only the language used to describe the decision.

Before action, name the accountable owner, affected population and workflow, exact offering or configuration, source data and rights, human decision point, exception and appeal path, complete cost, expected benefit, failure and stop conditions, retained evidence, and next review date. Keep official facts, provider statements, buyer observations, representative tests, measured outcomes, editorial inferences, and unknowns visibly separate. Reopen the record when the source, offer, model, integration, data, policy, population, responsible person, or measured result changes.
